Sun Ringle Black Flag Comp Wheelset

First things first: The new Black Flag Pro wheels are phenomenal, and they’re a steal.

The rims are wide and tires mount easily. They’re tubeless and hold air quickly and easily; we had no leakage issues during the test period, and we used just one small tube of sealant per tire during the initial installâ€¦that’s it. We also tested them with tubes. And by tested, we mean totally abused.
